THOMAS F. BURNS, OF OKLAHOMA, OKLAHOMA, ASSIGNOR OF ONE-HALF TO ROBERTP. CRUSE, OF ANADARKO, OKLAHOMA.

MUSIC-TURNER.

Application filed September 1, 1916.

To all whom it may concern:

Be it known that I, THOMAS F. BURNS, a citizen of the United States,residing at Oklahoma, in the county of Oklahoma and State of Oklahoma,have invented certain new and useful Improvements in Music- Turners; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to a music leaf turner and has for its primaryobject the provision of means, whereby the leaves of music may bereadily turned as they are played or read.

Another object of this invention is to pro-' vide a base or casingcarrying a plurality of "leaf supporting arms, having means attachedthereto, whereby one arm may be swung about a vertical axis at a time toturn the leaf of music carried thereby.

Another object of this invention is to provide means for returning theleaf supporting arms to their normal position after the leaves of musichave been once turned.

A further object of this invention is to provide means upon. anoperating arm and actuated by a cam to grip the uppermost leafsupporting arm to turn it upon actuating the operating arm.

A still further object of this invention is the provision of a musicleaf turner of the above stated character, which shall be simple,durable and efficient, and which may be manufactured and sold at acomparati ely low cost. 7

With these and other objects in view as will become more apparent as thedescription proceeds, the invention consists in certain novel featuresof construction, combination and arrangement of parts as. will behereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had tothe following description and accompanying drawings, in which Figure lis a top plan view of a music Specification of Letters Patent.

leaf turner, constructed in accordance with my invention, having the topof the base or casing removed,

Fig. 2is a longitudinal sectional. View taken on the line 22 of Fig. l,

i Fig. 3 is a fragmentary front elevation partly in section with theleaf supporting arms removed, illustrating the means of actuating theoperating arms,

Fig. 4: is a fragmentary enlarged vertical sectional view illustratingthe manner of mounting cams and ears upon the base or easing,

Fig. 5 is a. detail sectional view illustrating the means of pivotingthe leaf supporting arms to the base or casing,

Fig. 6 is a detail view partly in section illustrating one of theoperating arms, and

Fig. 7 is a detail sectional view taken on the line 77 of Fig. 1.

Referring in detail to the drawings, the numeral 1 indicates as anentirety a base or casing, consisting of a rear plate 2 and a frontplate 3, which plates are spaced apart by side strips 4. The front plate3 being provided with an elongated slot 5 adjacent its lower edge toallow for a plurality of leaf supporting arms 6 to extend through thefront plate 3.

A bracket 7 secured to the rear plate 2 adjacent the elongated slot 5has formed upon its upper edge an ear 8 to which is pivotally securedthe leaf supporting arms 6. Each of the leaf supporting arms 6 has aclasp 9 secured to their free ends and each clasp consists of a bottomplate 10 and a top plate 11. The top plate 11 being hinged to the bottomplate 10 as illustrated at 12 and the top plate 11 is normally held intoengagement with the bottom plate 10 by means of a leaf spring 13 so asto tightly clamp a leaf of music between the top and bottom plates 10and 11.

A pair of relatively spaced bearings 14 are secured to the rear plate 2of the casing or base 1 and are positioned upon each side of the bracket7 and have secured therein a shaft 15 which has each end squared to fitsquared openings in the bearings 14: to PI'B' the sleeve 19 and hassecured thereto a rod.

22 which has a ring 23 formed upon its free end. The ring 23 surrounds acam 24 secured to the shaft 15.

Each of the leaf supporting arms 6 have pivoted thereto a bell crank arm25 which is normally spring pressed by a leaf spring 26 for holding thebell crank arm 25 in a position so that one arm portion thereof extendsat right angles to the leaf supporting arm 6. lVhen the operating arm 17is swung from a vertical position to the right to occupy a substantiallyhorizontal position, the sleeve 19 is caused to slide in the directionof the free end of the operating arm by the cam 24 and as the operatingarm assumes a substantially horizontal position and the beveled end 18thereof has passed below the uppermost bell crank arm 25 on theuppermost leaf supporting arm 6, the extension 20 will be overlying thefree end of the operating arm thereby clamping the respective bell crankarm between the extension 20 and the free end of the operating arm 17.As the operating arm 17 is swung about the shaft 15 to turn the uppermost leaf supporting arm 6, the sleeve 19 will be drawn downwardlyupon the operating arm 17 when the operating arm 17 assumes a horizontalposition upon the opposite side or left hand side of the base 1. to freethe bell crank arm 25 therefrom, thereby allowingthc operating arm 17 toreturn to a substantially horizontal position upon the right hand sideof the base to grip the next adjacent bell crank arm 25 of the nextadjacent leaf supporting arm 6.

A plurality of pins 27 are formed upon the rear plate 2 of the base orcasing 1 and arranged in parallel rows to form a guard to slidablyreceive a rack bar 28. The rack bar 28 is in mesh with the gear 16 uponthe operating arm 17 A link 29 is pivoted to one end of the rack bar 27and to a bell crank lever 30 pivoted to the rear plate 2 of the base 1as illustrated at 31. A coil spring 32 is secured to one of the armportions of the bell crank lever 30 and to the rear plate 2 of the baseor casing 1. A link 33 is pivoted to the bell crank lever 30 and to anoperating arm 34 which is slidably secured in brackets 35 carried by therear plate 2 of the base or casing 1 and has its Slidable upon the freeend of the free end bent to form a finger grip 36. By pushing or pullingdownwardly upon the finger grip 36, the rack bar 28 is caused to slidebetween the parallel rows of pins 27 rotating the gear 13, swinging theoperating arm 17 about a vertical axis, turning the leaf supporting armwhich is attached there to in the manner heretofore described andswinging same about a vertical axis against the tension of the spring32. When the finger grip 36 is released, the rack bar 28 returns to itsnormal position under the influence of the spring 32, thereby returningthe operating arm 17 to its normal position, ready to turn the nextadjacent leaf supporting arm.

A gear 37 is journaledon the shaft 15 and has formed thereon anoperating arm 38 which normally extends in the opposite direction fromthe operating arm 17. sleeve 39 is slidably secured to the free end ofthe operating arm 38 and has an eXtension 40 formed thereon foroverlyingthe beveled end 41 thereof. A rod 42 is secured to the sleeve39 and has a ring 43 formed thereon for surrounding the periphery of acam 44 for causing the sleeve 39 to slide downwardly upon the operatingarm 38 when swung to a parallel position with the operating arm 17 whenit is in its normal position. A rack bar 45 is slidably secured to therear plate 2 of the base or casing 1 by rows of parallel pins 46 and haspivoted thereto a rod 46 which is in turn pivoted to a bell crank lever47. The bell crank lever 47 is pivoted to the rear plate 2 of the baseor casing 1 as illustrated at 48 and has secured thereto a coil spring49 which is in turn connected to the plate 2 of the base or casing 1. Alink 50 is pivoted to the bell crank lever 47 and to an operating arm 51which slides in the brackets 35. The free end of the operating arm 51 isbent to form a finger grip 52. hen all of the leaf supporting arms 6have been turned, they rest upon the extension 40 and to return them totheir normal or initial position, the finger grip 52 is pulled, causingthe rack bar 45 to swing the arm 38 to the right of the device,depositing the bell crank levers 25 upon the extension '20 of the sleeve19. As the arm 38 moves to the right side of the device, the cam 44causes the sleeve 39 to move downwardly upon said arm, disengaging theextension 40 from the bell crank levers 25, allowing the arms 6 to fallto their initial or normal position. By manually rocking all of the bellcrank levers 25 on their pivot, they will pass the extension 20, leavingthe arm 17 or extension 18 thereon disposed thereover. The weight of thearm 17 then being on the outermost bell crank lever 25 Wlll cause thesame to move on its pivot for admitting the bevel face of the extension1.8 to pass the same and the respective spring 26, connected to the bellcrank lever 25, forces it between the extensions 18 and 20, huspositioning the device for operation.

An operating rod 53 is slidable in the brackets 35 and has its free endbent to form a finger grip 54 and has its other end pivoted to a link55. The link is pivoted to a bell crank lever 56 which is pivoted to therear plate 2 of the base or casing l as illustrated at 57. An outwardlyextending extension 58 is formed on the free end of the bell crank lever56 of sufficient length to engage all of the bell crank levers 25 butthe outermost one when all of the leaf supporting arms 6 have beenturned, whereby upon pulling or pushing downwardly upon the finger grip54:, the extension 58 will rock the, bell crank levers 25 that are inengagement therewith, so that upon moving the arm 38 to the right bypulling on the finger grip 5a, the outermost or last leaf-support ingarm 6 that was turned from its initial position, will be engaged by theextensions L0 and 41 and returned to its initial position, providingmeans whereby the chorus of the music can be replayed and which isusually the last sheet of the series of sheets to a piece of music.

In operation, the device is placed vertically upon a music rack and theleaves of music are each received by the separate clasps 9 carried bythe leaf supporting arms 6. When it is desired to turn the first leaf ofmusic, the finger grip 36 is pushed or pulled downwardly causing theoperating arm 17 to engage the uppermost bell crank arm 25 and swing therespective leaf supporting arm secured thereto to a substantiallyhorizontal position upon the left hand side of the base 1, therebybringing the next adjacentleaf of music in view so that the same may beplayed or read by a person. After the leaves of music have been allturned, they may again be returned to their normal position by pressingor pulling upon the finger grip 52, causing the operating arm 38 toreturn the leaf supporting arms 6 to their normal position.

While I have shown and described the preferred embodiment of myinvention, it will. be understood that minor changes in construction,combination and arrangement of parts may be made without departing fromthe spirit and scope of the invention as claimed.
